The sci-fi/fantasy thriller ‘Apollo 18‘ uses a faux-documentary style to explore a covert trip to the moon that reveals disturbing new life forms, while Helen Mirren’s ‘The Debt‘ sees three former Mossad agents haunted by a dangerous secret mission from 30 years prior, and horror-flick ‘Shark Night 3D‘ features seven vacationers — most of whom will presumably become food — encountering shark-infested waters.
